What are the advantages of cold rolled silicon steel coils compared to hot rolled silicon steel sheets? With the innovation of electrical steel technology, these advantages have become more and more obvious. In addition, the quality of cold-rolled silicon steel coils is superior to the hot-rolled silicon steel sheet, and firstly, the cold-rolled surface is coated. , Good insulation performance, surface finish, flatness is better than hot rolling, while hot rolled silicon steel sheet is not coated, not comparable, second, cold rolling is infinite length of coil, hot rolling is flat, comprehensive utilization of cold rolling Obviously better than hot rolling, the entire plate "same-platen" cold rolling is only below 10μ, hot rolling can not reach, of course, "coal pressure coefficient" hot rolling is better than cold rolling, so on the whole, cold rolling quality is better than Hot rolling is positive. Cold-rolled silicon steel instead of hot-rolled silicon steel sheet has gradually become a market trend!
